An improved apparatus for cutting and stripping insulated wire. The apparatus includes a pair of cutting heads which are mounted on a supporting structure in opposed relation and each head includes a cutting blade and a stripping blade which is located downstream of the cutting blade. The insulated wire is fed between the cutting heads by a pair of endless belt feed units, one of which is located upstream of the heads and the other is located downstream of the heads. Each feed unit includes an endless timing belt, and the belts of each feed unit cooperate to move the wire in both a downstream and upstream direction during the programmed sequence of operation. The belts of each feed unit are moved in a direction toward each other by a chain drive and a torsion spring is operably connected to the chain drive in a manner such that operation of the chain drive in a direction to move the belts toward each other will increase the force of the torsion spring to provide a yieldable force against the wire. The cutter blades are mounted for pivotal movement in a lateral direction relative to the direction of wire movement, so that the cutter blades during the programmed sequence can be moved to an inoperative position. The insulated wire is fed from the upstream feed unit to the cutter blades by a guide tube assembly and the guide tube assembly can be pivoted from a guiding position to a non-guiding position where the guide tube assembly will not interfere with upstream movement of a cut length of wire during the program sequence. |
